Sreality

Overview

Sreality is the largest Czech real estate portal. We use its internal JSON API to fetch current flat prices (sale and rent) across regions.

API

Endpoint: https://www.sreality.cz/api/cs/v2/estates

Key parameters:

• category_main_cb=1 – flats
• category_type_cb=1 – sale (2 for rent)
• locality_region_id – for Praha (spans multiple districts)
• locality_district_id – for other cities

Challenges

• SPA with internal API (no official documentation)
• JSON uses _embedded field (requires serde rename)
• Listing names contain non-breaking spaces (\u{a0}) before “m2”
• Detail URLs constructed from hash_id + SEO locality slug

Data extracted

• Average price per m2 (sale and rent)
• Median price per m2
• Example listings near median for display on region pages
